ersa2021@ersa.org Special Session Proposal (S52) Building territorial and community resilience through disaster risk reduction in marginal areas of rural Europe SUB topic: - the methods to assess risk and measure resilience, for a full understanding, management, planning and monitoring of territorial dynamics Planning shrinking territory: Analisis criteria for planning infrastructures and resilient public space in Seismic Inner Areas of Central Italy Luca Domenella*, Marco Galasso**, Giovanni Marinelli*, Francesco Rotondo***, *SIMAU, Polytechnic University of Marche Via Brecce bianche 12, 60131 Ancona, Italy g.marinelli@univpm.it; l.domenella@univpm.it ** Independent Researcher, working with Universities e International research centres marco@akawebsite.eu *** DICEA, Polytechnic University of Marche Via Brecce bianche 12, 60131 Ancona, Italy f.rotondo@univpm.it Abstract Natural calamities that repeatedly hit the Country, ranging from earthquake to climate change induced events – like landslides and floods – resulted in huge damages, worsened by the infrastructural degrade and by the abandonment of some territories, especially in the inner areas of the Country. There is therefore a pressing need to improve the infrastructural resiliency, focusing on extraordinary manutention, on the technological development of the monitoring activities and of the supporting infrastructure, on the prevention, the civil protection and the public aid. Resilience nonetheless, is a much wider concept, as it was made dramatically evident by the current pandemic crisis. This includes, for example, the capability of the urban system to respond to unexpected seismic events or health issues; the solidity of the public space fabric, of services and strategic program supporting communities needed to promptly and efficiently respond to sudden crisis. In internal areas of central Italy, hit by 2016 calamities, the “safety strategy” is almost entirely consisting in definition of the “Emergency Limit Condition” (CLE). The synthetic analysis and the application of this instrument is limited inside the municipal administrative boundaries, limiting the seismic vulnerability assessment to individual centres, forgetting the territorial criticalities that could rise as a result of catastrophic events.
This paradigm, limited to municipal administrative boundaries, results in an increased
fragmentation of the territorial safety strategy, where the connection between infrastructural
networks at the regional scale is not always achieved.
Peripheral urban contexts of the Inner Areas are exposed to “isolation Risks” in case of
catastrophic events, as witnessed after the 2016 seismic events, where secondary
infrastructure network was heavily affected, bringing great problems for those living in the
areas.
It is evident that the reconstruction cannot leave aside the reorganisation of the infrastructural
network and a sustainable development of the territory, through a renewed accessibility to
the urban areas and the villages on the hillsides and the inner territories, that allow for a
resilient living, to overcome such seismic events.
The paper explores experimental methodologies to bring substantial modifications to the
villages and minor urban areas structure (for the damaged buildings and for the
infrastructural network) that the reconstruction allows, making it a unique occasion to renew
and reorganise the territory.
